Tested the new patch to build with old CodeWarrior and MPW,
and it seems it needed some hacks with those old headers...
Just in case you want to support the archeological versions -
here is a small add-on to the above patch, to fix those...
http://www.algonet.se/~afb/SDL-1.2.9-classic.patch
I couldn't get the old CW5 projects to build without a few
modifications - such as deleting the stray old header in:
"CWprojects/Support/Carbon/Include/ConditionalMacros.h" ?
But I updated both projects to CW6 too and built for Carbon,
and it ran all of the Mac test projects without any problems.
The MPW file seems to have compiled, with a small order change.
As long as you're still shipping the CWProjects and MPWmake
with the download, they should probably be updated/fixed ?
(another "solution" would of course be to just delete them)
I'll post my new projects along with the new Xcode projects
later on, along with XML exports of the various .mcp files.
(CW5 builds for Classic / "PPC", and CW6 builds for Carbon)
It'll be packaged as a part of the next SpriteWorld X release...
